My Mentor: I Wanna Do A Wall Garden, Because It Doesnt Take Up Too Much Space

i learned that Binghamton University researchers have been working on a self-healing concrete that uses a specific type of fungi as a healing agent. When the fungus is mixed with concrete, it lies dormant until cracks appear, when spores germinate, grow and precipitate calcium carbonate to heal the cracks (x)

How much longer until the utopic Solarpunk future where Capitalism is dead and we all live in ecologically sustainable high-tech forest cities? Asking for a friend.

New 'e-dermis' brings sense of touch, pain to prosthetic hands

Amputees often experience the sensation of a “phantom limb” – a feeling that a missing body part is still there.

That sensory illusion is closer to becoming a reality thanks to a team of engineers at the Johns Hopkins University that has created an electronic skin. When layered on top of prosthetic hands, this e-dermis brings back a real sense of touch through the fingertips.

“After many years, I felt my hand, as if a hollow shell got filled with life again,” says the anonymous amputee who served as the team’s principal volunteer tester.

it's weird how people will be like "but we need Suburban Lawn so kids can play outside!" as if basically every kid isn't bored to tears by being confined to a yard that's nothing but flat grass.

like have you talked to a kid, have you spent time with kids, do you remember BEING a kid? "playing outside" isn't about Throwing Ball 1000 times it's about squishing mud, using sticks as swords and guns, making potions from plants, catching bugs, climbing trees, and building forts from brush and branches.

A highly manicured lawn has nothing to offer the senses and brain of a developing child. If there are no "weeds," what are they supposed to gather to make into potions?? I'm not even joking, what do you, a child, DO in a yard without wildflowers and mud and dead branches. I feel like my brain wouldn't have developed correctly if my outdoor space growing up wasn't full of chicory and asters and dandelions.

At least video games offer some dim imitation of a variety of stimuli

What do you think of vertical axis wind turbines? Seems to me they'd complement small domestic PV installations nicely and could use some wider usage

I’ve heard some people get quite preachy about vertical axis wind turbines being no good, but personally I’m rather fond of them. I definitely agree that for domestic use, they make more sense than regular windmills. They’re also much better suited to urban environments.

The typical style of wind turbines are great when you have lamellar flowing air currents, like near the coast or on flat plains, but city wind is more gusty and turbulent. Vertical axis turbines definitely seem ideal for that!

I think some of the reservations people have stem from the fact that, in the past, vertical axis wind turbines have typically been less reliable, and the turbine blades are more prone to fatigue. Though using modern engineering materials and turbine designs, I’m not convinced those old problems still apply.

Some designs for small scale applications are also impressively discreet and quiet – though seemingly rather expensive!

Those “clean energy is ready to go whenever” memes annoy the hell out of me because they’re typically ignoring two-thirds of the issue.

In a nutshell, there are three legs of energy infrastructure:

Power generation: Getting the power in a useful form

Power transport: Getting the power in a useful form where you need it

Power storage: Getting the power in a useful form when you need it

In  some respects, clean power generation is, indeed, a solved problem; clean transport and storage, however, are not. For many applications, no good non-polluting alternatives exist, and when they do, the environmental costs of setting up and maintaining those alternatives are not, themselves, insignificant. (Look up what goes into your average rechargeable battery some time!)

No, that doesn’t mean it’s an impossible problem, nor does it in any way excuse the continued intransigence of the the petrochemical industry. It does mean that there’s still a great deal of important work to be done, and it’s galling that so many self-labelled environmentalists are just casually contemptuous of it all - often to the extent of accusing researchers in power transport and storage of being oil industry shills for having the temerity to discuss the remaining challenges - because “clean energy is ready to go whenever”.

Rising Seas Are Going to Drown Way More Cities Than We’d Thought: Study

In a low-warming scenario, we expected rising tides to cover areas currently occupied by 37 million people. The real number is closer to 150 million.

But none of the challenges posed by our warming climate has loomed larger in the popular imagination than sea-level rise. With global populations and wealth heavily concentrated in low-lying coastal cities, humanity has been preoccupied by the prospect of the oceans reclaiming the high points of our civilization. And for good reason: The best available models suggest that 37 million people currently live in places that will be below high tide by 2050 — in an optimistic low-carbon-emissions scenario.

Or rather, that’s what such models suggested before this week. On Tuesday, a new study revealed that those alarming statistics — which had gotten so many of us all worked up about our favorite cities’ impending doom — were wildly inaccurate.

The actual impacts of sea-level rise are going to be much, much worse.

Listen, folks, few understand the enormity of what is happening, nor how fast it’s occurring, and, look, I don’t count myself among those few. 

The rest of us do not realize the catastrophe that is happening right now. 

Maybe that’s not fair to say: the people of California probably understand all too well. Even if their home is not on fire, certainly they see the hellish red glow in the sky and cannot avoid the acrid smell of wildfire smoke.

For sure, the indigenous folk who subsist on whale meat understand the crisis, since the bowheads they hunt have not appeared. None of them. They are way out to sea, trying to avoid the warming oceans and underwater heat waves. 

The people of Key West, who have endured a “king tide” flooding their city streets for 60+ days straight, probably think there’s a big problem. Some of them, no doubt, are hanging on to the foolish belief that this tide is going to subside – it’s not – it’s rapid sea level rise. 

It’s not our fault though, that we do not know … did not know, because, everything we have been told, the stuff that has made it out of the media in the past decade or so, has all been based on these same “optimistic low-carbon-emissions scenarios.”

This is not the world we live in. We live in the high-emission catastrophic scenario. We were shown these, when we were shown anything at all, but we were told these catastrophic emission scenarios would never, ever – couldn’t possibly – ever be so. 

Yeah, well, we were wrong about.

Same money live greener

Easy switches to save money and the planet

Try to buy everything secondhand, or receive 2nd hand goods, this will save your wallet and will do no harm to the planet

Make thrift shops your main shops, you can find anything from clothes to appliances to furniture

Buy only what’s necessary new, so think things like socks, undies and tennis shoes

Do you have an empty jam jar? Boom, automatic glass jar for dry goods

Try upcycling your old possessions you are bored of but can’t let go of

Buy measured amounts of dry goods, especially if you know you will only need so much for a recipe

Try growing your own food for fun, sometimes you can score free seeds from farmers, your local arboretum, or from produce you already have.

Do you have any other thoughts or ideas on cheap zero wasting? Leave them in the comments!!
